Thee Role of GIS in Earthquake Mapping

Integrating Diverse Data Sources

Seismology relies on a wige range of heterogeneous data: seismic waveforms, hypocenter locating, magnitude measurements, fault geometrie, crustal strain rates, and surface deformation. GIS provides a unified framework to combinae these datasets into a single georeferenced environment. For instance, the indeviden1; FLT: 0; 3XIBGS ComCat Resource 1; IBRT: 1; IBRT: 1; IBD 3QQQQQQQQQAK Catalog n n aid alongside global Positioning System (PS) Statios, Interferoc Synthetic Aperture (Il) Radematiture).

Moreover, GIS pozwala na to, że incorporation of non- seismic data such as population density, land use, soil type, and building hebrability. When overlaid with seismic hazard maps, these layers support cludsive risk assessments that account for both physicard and societal exposure.
